WALL-BED ATTAGHMETLTT.

Application filed A r-n 2,

This invention relates to improvements in folding beds, and more particularly to means for locking and bracing the pivotally retained mattress frames thereof against movement with respect to the supporting frames at the head of the bed, to which they are hingedly attached.

The particular type of bed to which this invention is most applicable is that having a rigid head-end frame of a character most suitable for attachment to the wall of a room by suitable attaching brackets, and that ma be readily detached therefrom and moved to a new position for installation as an ordinary bed, to meet emergency makeshifts, with means provided for so looking the pivotal frame with respect to the head end frame that the entire frame becomes a rigid unit.

The object of the present invention is the provision of a special combination locking and bracing means, similar to the togglejoint arrangement of levers, which, when brought to proper position, will positively brace and lock the pivotal mattress-frame of a wall-bed against upward tendency of movement induced by the urge of the counterbalance springs ordinarily used in such bed construction. 7

In the accompanying drawings, forming a part of this specification, and in which similar characters of reference refer to like parts, throughout,

Figure 1 is a perspective view of the head end of a hinged-bed mattress-frame, showing my locking and bracing attachment in use;

Figure 2 is an enlarged perspective detail of one ofthe attaching brackets for rigidly securing the bed frame to the wall of a room, as shown in Figure 1; and

Figure 3 is an enlarged perspective view of one of the locking and bracing attachments.

Figure 4 is a side elevation of the head frame of the bed, showing the mattress frame raised to vertical position, with the toggle-joints in lowered locking position; and the dot-and-dash position showing the mattress frame in its horizontal position, with the toggle-joints in bracing position.

Referring more particularly to the drawings, 1 indicates the head-frame of a bed embodying the features of my invention, 2 the ordinary mattress-frame pivotally connected at 3, as shown in Figure 1, to section of the rigid head-frame 1, which, when used as a wall-bed, is attached to a wall by means casters.

of extensions 1, 5 and 6 projecting from the bed-frame 1 and adapted to be engaged by angle-iron wall-brackets hereinafter described.

Therigid head-end frame is comprised of the supports 1, bracing bar 7 and uprights 8,

rigidly riveted together and mounted upon Springs 16, having their opposite ends secured, respectively, to the bracing-bar 7 and the mattressframe 2, are provided as counter-balancing means, the spring urge tending to counter-balance the weight of the bed mattress-frame.

In order to offset the tendency of the springs to raise the mattress-frame and to insure rigidity between the mattress-frame and the head-frame, I provide a special lockmg and bracing means in the form of a pair voftoggle-joints comprised, each, of links 9,

and 10, pivoted, respectively, to the headframe at 12 and to the mattress-frame at 11, the two links constituting the pair comprising the toggle being pivoted at 13 to form a hinge, the links 9 bearing extensions 15 carrying notched out sections adjacent the pivot 13 adapted to engage a stop, or pin, 14, when the links are straightened out in alignment, thereby locking frame 2 against upward movement upon its Pivot 3.

These toggle-joints act as rigid braces to hold the mattress-frame'in its lowered, or

horizontal, position, and also act in like manner to rigidly brace and hold said frame in its upright, or vertical, position. a

1n the operation of raising the bed-frame, the pivot points 13 of said joints allow the links to break backwardly, to compensate for the arcuate movement of the points 11 relative to the points 3, until the pivot points 11 assume positions directly below the pivotal points 3 of the mattress-frame, at which positions the links of the toggle-joints are again straightened out and act as rigid braces to hold the mattress-frame in its raised, or vertical, position. To release the links -9 and 10 from their locked position, as shown in Figure 1, a sharp thrust is applied beneath, or adjacent, the pivot point 13, folding these links in the direction indicated in Figure 3, thus releasing the mattress-frame 2 from its rigid connection with the headframe 1 and permitting the frame 2 to be swung freely upon its pivot to the vertical position.

The wall-brackets 17 and 23, previously referred to as adaptable means for securing the construction in position as a wall-bed, are provided with flanges 18 and 19 attach able to the wall support by screws 24, the upper surfaces of said brackets being provided with slots 22, in which are loosely fitted locking-bars 20, pivotally secured at 21 to the flanges 18 of the brackets 17 Having thus described my invention, I claim, and desire to secure by Letters Patent,

In a wall-bed adapted for attachment to 55d detachment from a wall-support, the combination, a head-frame, an upending mattress-frame pivotally connected therewith, counter-balancing means for said mattress-frame, and locking and bracing means therefor, in the form of toggle-joints pivotally connected to said head-frame and mattress-frame adjacent the head-end thereof, the said toggle-joints being comprised f pairs of pivotal links, one link of each pair having an extension, and the other link a stop adapted to engage the extension carried by its companion link when the mattress frame is in a horizontal position, and adapted for like engagement when said frame is raised to a vertical position,'to rigidly brace and lock said mattress-frame against movement from either of said positions.

In testimony whereof, I have hereunto set my hand.
